| Use of Inverters
Electrical is not my strong suit. I understand the concept of how many watts an inverter puts out and the basic use of limiting actual usage to I've been told about 75% of the rated wattage available. That is of course a rule of thumb. I suspect the inverter has some surge capacity above it's rated value.
However, How do I compute the draw down on my 12V batteries if you wife wants to use a hair dryer for 15 or 20 minutes. I guess if there is such a thing, I'm looking for the magic bullet formula that will tell me that if I use 15 amps at 120V I will need X amount of amps in the batteries to make that available.
